CVE-2025-14047 is a vulnerability classified under CWE-862 (Missing Authorization) found in the WordPress plugin 'User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration' developed by tareq1988. The issue stems from the absence of a capability check in the 'Frontend_Form_Ajax::submit_post' function, which handles frontend post submissions. This missing authorization allows unauthenticated attackers to invoke this function and delete attachments associated with posts, leading to unauthorized data loss. The vulnerability affects all versions up to and including 4.2.4 of the plugin. Since the attack vector is network-based (remote, no authentication required), and no user interaction is necessary, exploitation is straightforward. The impact is primarily on data integrity, as attackers can delete attachments, potentially disrupting website content and user experience. There is no direct impact on confidentiality or availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The CVSS v3.1 base score is 5.3, indicating medium severity, with attack vector network, low attack complexity, no privileges required, and no user interaction needed. The plugin is widely used in WordPress environments for managing user-generated content, membership, and profiles, making this vulnerability relevant for websites relying on these features.

For European organizations, this vulnerability poses a risk of unauthorized deletion of attachments on WordPress sites using the affected plugin, potentially leading to loss of critical user-generated content, disruption of membership or profile data, and degradation of user trust. Organizations relying on this plugin for frontend posting, user directories, or membership management may experience operational disruptions and reputational damage if attackers exploit this flaw. While the vulnerability does not directly compromise confidentiality or availability, the integrity loss can affect business processes, especially for content-heavy or community-driven websites. Additionally, the ease of exploitation without authentication increases the risk of automated attacks or mass exploitation attempts. Given the widespread use of WordPress across Europe, particularly in small and medium enterprises and community organizations, the impact could be significant if not addressed promptly.

1. Monitor the plugin vendor’s official channels for security patches and apply updates immediately once available. 2. Until a patch is released, restrict access to the WordPress frontend submission endpoints by implementing web application firewall (WAF) rules that block suspicious or anomalous requests to 'Frontend_Form_Ajax::submit_post'. 3. Employ strict role-based access controls and verify that only authenticated and authorized users can submit or modify posts and attachments. 4. Regularly audit and monitor logs for unusual deletion activities or unauthorized access attempts targeting the frontend submission functionality. 5. Consider temporarily disabling the frontend post submission feature if it is not critical to operations. 6. Use security plugins that can detect and block unauthorized requests or anomalous behaviors related to frontend posting. 7. Educate site administrators on the risks and encourage prompt incident response readiness. 8. Backup website data frequently, including attachments, to enable recovery in case of data loss.
